MTYLD
Employee & Partner Asset Program
Revenue-Backed Token • ETH Vault • Business Credit Line
Executive Summary
MTYLD (Mechanical Temp Yield) is a digital asset designed for the employees, partners, and supporters of Mechanical Temp, an HVAC company in Southfield, MI. Unlike traditional bonuses or cash rewards, MTYLD is a USDC-backed token whose net asset value (NAV) grows from real HVAC revenue and on-chain credit line interest.
Holding MTYLD also unlocks access to The Conservator — an AI-managed ETH yield vault — and the MT Business Credit Line v3, where MTYLD or mtETH-S can be posted as collateral to earn a share of loan interest.
MTYLD is the revenue-backed token. The Conservator is the ETH yield vault. The Credit Line is the on-chain bank. Each unlocks the next.
The Product Suite
MTYLD Token
USDC-backed token. NAV grows from HVAC revenue and Credit Line interest. Redeemable for USDC at current NAV when the epoch is open.
The Conservator (mtETH-S)
ERC-4626 ETH vault for MTYLD holders. AI agent deploys WETH to Compound V3. Yield grows the NAV of mtETH-S shares.
MT Credit Line v3
Dual-collateral business credit line. MTYLD (70% LTV) or mtETH-S (60% LTV) backs USDC loans. 8% APR, 90-day max term.
How MTYLD Works
MTYLD's NAV grows from two real revenue streams, both injected on-chain into the treasury at the MTYLD vault.
HVAC Service Revenue
A portion of Mechanical Temp's physical service revenue is converted to USDC and injected into the vault via injectRevenue(). The contract enforces a configurable NAV delay between queue and apply, preventing opportunistic minting ahead of a revenue event.
Credit Line Interest
When Mechanical Temp draws on the credit line and repays, 30% of accrued interest distributes to collateral providers (MTYLD and mtETH-S depositors), split by USD value at repayment time. Pool earnings can be reinjected to grow NAV.
NAV Injection — On-Chain & Transparent
Revenue is queued, the NAV delay window passes, then anyone can call applyPendingRevenue() to lift the NAV. Every injection is visible on Arbiscan with a timestamp and amount.

The Conservator — mtETH-S
Access requires holding MTYLD. The vault enforces minMtyldRequired on deposit.
The Conservator is an autonomous AI agent (Claude-powered) managing an ERC-4626 ETH vault on Arbitrum One. Users deposit WETH and receive mtETH-S shares. The agent deploys idle WETH into yield strategies; yield grows the share NAV rather than minting new shares.
Deposit WETH
Connect your wallet at conservator.html. Approve and deposit. Minimum deposit is 0.01 WETH.
Receive mtETH-S Shares
Share count stays fixed in your wallet; each share becomes worth more WETH as yield accrues. NAV = (idleWETH + sum of strategy balances) ÷ totalSupply.
Agent Deploys to Strategies
The active strategy is Compound V3 WETH supply at 0x3F26…4F2. The vault uses a v5 plugin architecture, meaning new strategies can be added without redeploying the vault. Strategies pull WETH via transferFrom only after owner approval — the agent cannot send funds to arbitrary addresses.
Use mtETH-S as Collateral
mtETH-S can be deposited into the Credit Line at 60% LTV. While locked there, it continues earning Compound V3 yield and earns a share of credit-line interest.
Established lending market for WETH on Arbitrum. The vault queries Comet's getUtilization() and getSupplyRate() live for transparent rate display.
24-hour lock applies after each deposit (anti–flash loan). Withdrawals can be batched through the agent if idle WETH is insufficient — the agent pulls from strategies on request.
The first depositor burns 1,000 wei (sub-$0.000001) as standard ERC-4626 inflation-attack protection.
Additional yield strategies can be added by the owner via addStrategy(). The vault contract itself is immutable once deployed.

Operational Treasury — Market Making
Separate from MTYLD and the Conservator, Mechanical Temp's Deployer Wallet (0xcfe0…557a) holds a treasury position in the GMX ecosystem: GM ETH/USD, GM BTC/USD, and staked GMX. These positions earn fees from perpetual traders and accumulate buyback capacity.
These are operational treasury assets of Mechanical Temp the company, not collateral backing MTYLD or mtETH-S. They are shown transparently on the Conservator page and on the Portfolio page under "Market Maker Positions" so depositors can see the strength of MT's broader balance sheet — which improves the company's ability to service the Credit Line.

MT Business Credit Line v3
The on-chain bank of Mechanical Temp. Three roles — USDC lender, collateral provider, or borrower.
The credit line is a three-sided market. USDC depositors fund the pool. MTYLD and mtETH-S holders post collateral. Mechanical Temp (the borrower wallet, hardcoded as 0xcfe0…557a) draws USDC for operations and repays with interest, which is then split between participants.
USDC Depositors — Earn 70% of Interest
Anyone can deposit USDC. On repayment, 70% of interest distributes pro-rata. Withdrawals are open when no loan is active.
mtETH-S Collateral — 60% LTV • Share of 30% Interest
Deposit mtETH-S as collateral. Each share contributes 60% of its ETH value to borrowing power. While locked, it continues earning the Conservator's underlying Compound V3 yield, plus a proportional share of the 30% collateral interest split.
MTYLD Collateral — 70% LTV • Share of 30% Interest
MTYLD gets the highest LTV (70%) because its NAV is USDC-stable — backed by revenue, not crypto market price. MTYLD collateral earns the same proportional share of the 30% interest pool, weighted by USD value at repayment time.
Borrower — Mechanical Temp
A single borrower address is hardcoded into the contract: Mechanical Temp's deployer wallet 0xcfe0…557a. The borrower can call openLoan() up to the combined borrow power, and repayLoan() or repayPartial() any time within the 90-day term. This means MT is both protocol operator and counterparty — see the Risk section below.
- Rate: 8% APR
- Max Term: 90 days
- mtETH-S LTV: 60%
- MTYLD LTV: 70%
- Partial Repay: Supported
- Interest Split: 70 / 30 (USDC / Collateral)
- mtETH-S USD Price: Chainlink ETH/USD × vault NAV
- MTYLD USD Price:
pricePerToken()NAV - Withdraw Lock: Active during open loans
- Interest Math: Ceiling division (never rounds to zero)
Live Status — Current Loan
At time of writing, the Credit Line has one active loan: a $200 draw with $0.04 accrued interest at the 8% APR. Real-time status is visible on the credit-line page and the portfolio page. All draws and repayments are recorded on Arbiscan.

Why Participate?
1. Real Revenue, Not Yield Farming
MTYLD's NAV grows from physical HVAC work converted to USDC and from real interest paid on real loans. There is no token inflation, no farming emissions, no ponzinomics.
2. Liquidity
Mint and redeem MTYLD for USDC on-chain at the current NAV when the epoch is open. Bridge USDC to Base or Ethereum mainnet via the Relay links on every page.
3. ETH Yield via The Conservator
Holding MTYLD unlocks a second yield stream denominated in ETH. Deposit WETH, earn Compound V3 yield automatically, redeem for more WETH than you put in.
4. Earn as a Collateral Provider
Lock MTYLD or mtETH-S in the Credit Line and earn a share of every loan repayment. MTYLD earns at the highest LTV because its NAV is USDC-stable.
5. USDC-Stable by Design
MTYLD is not a volatile crypto asset. Its NAV moves with the treasury, which is denominated in USDC. There is no liquidation risk and no market-driven price discovery.

Risks
MTYLD, The Conservator, and the Credit Line are real on-chain products. Real means real risk. Read this section carefully.
Business Risk (MTYLD)
MTYLD's NAV grows from HVAC revenue. If Mechanical Temp's revenue slows or stops, NAV growth slows or stops. NAV cannot go below the backing in the treasury, but it can stagnate.
Borrower Counterparty Risk (Credit Line)
Mechanical Temp is the sole authorized borrower. If MT fails to repay a loan within the 90-day term, the loan becomes isOverdue(). The contract does not currently auto-liquidate collateral — recovery would depend on MT's ability to repay and on collateral remaining valuable. Borrowing power is conservatively set (60% / 70% LTV), but in a severe scenario USDC depositors could be exposed to delayed repayment.
Smart Contract Risk
Contracts have not been formally audited at the time of this publication. All source is verified on Arbiscan; review before depositing meaningful capital. Standard ERC-4626 vault precautions (first-mint burn, withdraw lock) are in place.
Oracle Risk
mtETH-S collateral pricing depends on the Chainlink ETH/USD feed. MTYLD collateral pricing depends on the vault's own pricePerToken(). Stale, manipulated, or paused oracles could mis-price collateral. Chainlink staleness check is enforced in the Credit Line contract.
Strategy Risk (Conservator)
The Conservator currently deploys WETH into Compound V3. Compound V3 smart contract risk, governance risk, or interest rate volatility flows through to mtETH-S NAV. Additional strategies, when added, will carry their own risks.
Operator Risk
Mechanical Temp retains owner privileges: pause, fee changes, whitelist, strategy registration, NAV delay adjustment, max supply changes, agent updates. Operator actions are visible on-chain. The token rescue function has a mandatory delay to allow holders to react.
Liquidity Risk (mtETH-S)
When idle WETH in the Conservator is below your requested redemption, the AI agent pulls from strategies. This can take time. Plan large withdrawals accordingly; the dashboard surfaces this state explicitly.
